Title: 20a or 30a ESC for 30amp lipo
Post by: sayeed on September 17, 2015, 08:40:48 AM
Someone help me to know which ESC gives optimum performance either 20a or 30a for a 30amp lipo battery I.e.(1500mah 20c 3 cell)

My power setup:
Wolfpack White 1500mah 20C 11.1V
Avionic White 20Amp ESC
Avionic C2822 KV 1400 brushless motor(150 watt, 14amp)
Prop 8*3.8 E

I'm not sure about the thrust results.

Please suggest me esc,?

@sayeed,
Since the motor is rated for max current of 14amps, a 20amp ESC is enough.

(The C rating of the battery indicates the max current it is capable of providing. It does not mean that the battery will force 30amps through the circuit. Current is drawn, not pushed. As long as you stay within the voltage and prop size limits recommended for the motor, it will not draw over 14amps. Incidentally, the indicated C rating is usually quite optimistic)

Regards.
